[ That is, when the fuel door device 100 is set to the locked state, the control unit (not shown) controls the locking device 102 to insert the locking protrusion 103 into the locking part 133 so that the fuel cap door 130 So that the fuel injection port 125 can not be opened. On the other hand, when the fuel door device 100 is set in the open state, the control unit controls the locking device 102 to separate the locking protrusion 103 from the locking part 133, 125 can be opened.

The fuel door apparatus 100 may further include an auxiliary guide pipe 140. The auxiliary guide pipe may include a guide body 141 provided in a hollow cylindrical shape. One end of the guide body 141 is inserted and fixed in the guide pipe 110 and the other end of the guide body 141 may be connected to a fuel tank (not shown) provided inside the vehicle 1. [

Hereinafter, the lubrication process of the vehicle 1 according to the embodiment of the present invention will be described.

2, 4, and 5, when the user does not supply fuel to the vehicle 1, the fuel cap door 130 is in a state of being coupled to the auxiliary neck 120. The locking protrusion 103 of the locking device 102 is inserted into the locking part 133 and the auxiliary neck 120 is at the entry position IP. At this time, the cover panel 131 of the fuel cap door 130 may be provided on substantially the same plane as the side panel 101 of the vehicle 1 to form a part of the side panel 101 of the vehicle 1. [

6 to 8, when the user intends to lubricate the vehicle 1, the user controls to release the locking device 102 so that the locking protrusion 103 is separated from the locking part 133 The fuel cap door 130 can be pressed once inside the side panel 101 of the casing 10 of the vehicle 1. [ Accordingly, the auxiliary neck 120 slides relative to the guide tube 110 and moves to the outward position WP of the side panel 101 by a predetermined length. Accordingly, the fuel cap door 130 can protrude from the side panel 101.

10, the user rotates and separates the fuel cap door 130 from the auxiliary neck 120, and then inserts the fueling pipe 109a of the fueling gun 109 into the fuel injection pipe 124 You can do gas filling.

Thereafter, the user who has completed the fueling may press the fuel cap door 130 once in the inward direction of the side panel 101 after rotating and joining the fuel cap door 130 to the auxiliary neck 120. At this time, the auxiliary neck 120 can be fixed again to the retracted position IP by the fixing member 115.

According to the above-described configuration, when the vehicle 1 is injected into the vehicle 1 by using the main gun 109, the vehicle 1 according to the embodiment of the present invention has the auxiliary neck 120 of the fuel door apparatus 100, It is possible to prevent the side panel 101 from being damaged due to interference between the main gun 109 and the side panel 101 since it is drawn out adjacent to the panel 101. [

In addition, the vehicle 1 according to the embodiment of the present invention can cover the fuel injection port 125 with only the fuel cap door 130 and cover the opening formed in the side panel 101 for lubrication, thereby reducing the material cost .

The foregoing has shown and described specific embodiments. However, it should be understood that the present invention is not limited to the above-described embodiment, and various changes and modifications may be made without departing from the technical idea of the present invention described in the following claims .
